XJ "Check Engine" feil...HJELP !!

[512TR]

Tja..har ikke så mye å bidra med siden jeg enda ikke har jobbet med OBDII systemet, men det kan visst varriere fra forskjellige modeller...Jeep, Crysler, Dodge bruker det samme systemet og de samme kodene.
Hvis du ser på den lange lefsen med kodene, ser du bla. koder for 10 syl, disse kodene brukes også på Dodge sine V10'ere.



Her er noen andre måter du kan prøve for å få frem kodene..

<!--coloro:#000099--><!--/coloro--><i>This seems needlessly complicated, so you may simply want to invest in an OBD compatible code reader. They're not too expensive and some can record sensor readings and save them to a file (or replay them for you), making diagnosis easier. Still, it's great to be able to read your own error codes - you can troubleshoot it yourself without any tools, or you can tell when your mechanic is totally off-base. </i>

<i>On the 300, Magnum, and Charger, you cannot see the codes without a reader. Most codes are visible with a standard code reader. The dealer can see more codes (those that are not required by Federal law).
<b>You may have to have the parking brake firmly set for the codes to show! </b> (Thanks, Steven Midway)

Codes are usually displayed on digital odometers on newer models.
On many 2001 and newer models, holding in the trip odometer reset button while turning the key to RUN will start a self test, with a readout on the odometer. It will also activate all instrument panels, one at a time. We do not know if this will show computer codes, or whether it only tests the instrument panels. At the end, it may show a few odd codes that are firmware versions and not error codes.

On most cars, the codes will read out if the engine light is on - all you have to do is put the key into the RUN position.

<b>Normally, to get codes, you put the key on OFF and then rapidly do OFF-ON-OFF-ON-OFF-ON (on some cars you have to do four or five, not three, OFF-ON cycles). On our test 2002 car, the key did not go back to unlock, so it was ACC-ON-ACC-ON-ACC-ON. </b>

Jon Yoon: The 1998 Caravan does the same check engine light code trick, but it also does an instrument diagnostic check if you hold the trip and reset buttons and turn the key to the run position and wait 5 seconds. This helped me figure out that my input and output speed sensors were broken but the actual speedometer dial could move.

<b>For the 1999 Jeep Grand Cherokee and up, you do the switching the key on and off 3 times, but not quickly. You turn it to on so the odometer turns on, turn it off, and then back on, wait for the light to turn on, etc. On the fourth time you'll get a code, or you'll get the word "done." (Monica MacDonald) </b>

A loose gas cap may light up the Check Engine light! (Thanks, Lyn Clark)
When the computer indicates major failure, it can activate Limp In mode, which guesses about data to compensate for sensor failure, allowing you to get the car to a mechanic. One major symptom of this is the transmission sticking in second gear. This is a feature!
<b>2002 Ram, put transmission in neutral, parking brake on, then do the acc-run key sequence 3 times. </b>
Dan Stewart wrote about the 1999+ Voyager/Caravan with digital gear selection display:
<b>There are 2 functions that can be accomplished with the key-on sequence. Get Diagnostic Trouble Codes by placing the key into the ignition. Push and hold the both the "Trip" and the "Reset" buttons with the left hand and turn the key to the "ACC" position (first position between "LOCK" and "RUN"). Continue to hold both buttons in and count to 5. Release both buttons, display should read trip mileage instead of total mileage. Push the "TRIP" button and the odometer will display DTC'S in rotating sequence instead of displaying total mileage. </b>

The second function is an instrumentation diagnostic. Place key into ignition, press and hold both "TRIP" and "RESET" while turning the key to the "RUN" position. Continue to hold both buttons in until odometer displays "CODE". Release buttons. The display will then display "999". Afterward it will display "CHECK 0" and test the analog gauges. It will then display "CHECK 1" and test the digital displays </i> <!--colorc-->

<!--quoteo-->QUOTE<!--quotec-->Test tur 1:
Ingen feil melding, men speedometer viste "nada".....da er det vel avleseren på transferkassen som feiler ?

Test tur 2:
"Check engine". Motoren går fint...men kan synes som den faller litt i turtall ved slipp av gasspådrag og clutch inne" Etter en liten oppgassing kommer feilmelding. Har jeg et problem med sensoren på katalysatoren?. Den var frakoblet i pluggen ifb med demontering av girkasse.<!--QuoteEnd--><!--QuoteEEnd-->


Det er sikkert lurt å sjekke at Speed sensoren på 231 kassen din står rett vei, står den feil vil ikke spedometeret virke og Check Engine lyset komme på. (Feil code0500)



Hvis du har plugget inn O2 sensoren( etter katalysatoren) skulle den vel funke...(evnt. feil code P1196)
